King of Mithilā. He was the son of Nimi and belonged to the Maghādeva dynasty. Whereas other kings of his race left the household at the approach of old age, he broke the tradition by not doing so. He was the last king of this dynasty. His son was called Samaṅkara. M.ii.82; DA.iii.851; Mhv.ii.11; Dpv.iii.37; but see J.vi.129, where he, too, is said to have renounced the world and brought the family to an end.

Kāḷārajanaka was so called because he had long, projecting teeth (MA.ii.738).
